ABSTRACT
Purpose: Angle kappa has been considered to play a role in causing glare and haloes despite accurate centration during implantation of multifocal intraocular lenses following phacoemulsification. There is a lack of substantial data regarding whether angle kappa is a constant entity or changes following ocular surgical procedures. To answer this question, in this prospective observational study, we measured change in angle kappa following phacoemulsification, and studied the ocular biometric parameters correlating with this change. Methods: Angle kappa was measured objectively using synoptophore. Ocular Biometric parameters (Anterior Chamber Depth, Corneal White?to?White measurement, Lens Thickness, and Axial Length) using LenStar LS 900 Haag Streit Anterior Segment imaging system. outcome measures were a quantitative change in angle kappa from the preoperative value by one degree or more and observation of correlation between change in angle kappa and ocular biometric parameters. The Wilcoxin Signed Rank Test was used to determine the difference between pre?operative and post?operative measurements for angle kappa. A p?value of less than 0.05 was considered statistically significant. Pearson's correlation coefficient was employed to find the relationship between preoperative ocular biometric parameters and a change in angle kappa. A linear regression model was used to derive an equation considering corneal white?to?white measurement as the predictor and change in angle kappa as the outcome measure. Results: A significant change in angle kappa was recorded, and a significant correlation was found with corneal white to white measurements. This change could be predicted preoperatively, for a known corneal white to white measurement using the standard equation y=mx+c. Conclusion: This study explains the possible cause of dissatisfaction among seemingly ideal patients who undergo multifocal IOL implantation and the potential for better decision? making during patient selection for multifocal IOL implantation.
ABSTRACT
Purpose: To compare the efficacy of Kane formula with Sanders Retzlaff Kraff/Theoretical (SRK/T) and Barrett Universal II in predicting intraocular lens (IOL) power in Indian eyes. Methods: This retrospective study conducted in a tertiary care eye hospital. Data from patients having uneventful cataract surgery with Tecnis ZCB00 IOL implantation were obtained from Lenstar and electronic medical records. Eyes were divided into subgroups based on axial length (AL) as short (<22.0 mm), medium (22� mm), and long (>24 mm). The predicted refractive outcome for each patient was calculated after optimizing the lens constant. Prediction error was calculated by subtracting the predicted spherical equivalent from achieved spherical equivalent 1 week post?surgery. The mean absolute error (MAE) and median absolute error (MedAE) and percentage of eyes within 0.25, 0.5, 1, and 2 D were calculated for each formula. Friedman test, Cochrane Q test were used for statistical analysis. Results: Out of the 350 eyes included in the study, we found that without lens constant optimization, Barrett formula performed better than SRK/T and Kane (P < 0.0001). Over the entire range of axial lengths, Kane formula performed slightly inferior compared to Barrett and SRK?T, both of which performed equally well (P = 0.006). On subgroup analysis, Kane formula performed inferiorly for medium eyes as compared to the other two. No significant differences were noted between the formulae for short and long eyes. Conclusion: Kane formula did not outperform Barrett Universal II and SRK/T in Indian eyes
ABSTRACT
Neonatal deaths account for a major proportion of child deaths globally. Major causes of neonatal deaths are preterm birth, asphyxia, sepsis, pneumonia, congenital anomalies, diarrheal diseases, and tetanus. Without a sound knowledge about the changing trends in morbidity and mortality, it will be difficult to formulate appropriate strategies in management, prevention, and review. The present study was aimed at providing statistical data related to mortality pattern seen in hospitalized neonates. Methodology: A descriptive case series study was conducted with records of the patients who were admitted in the Paediatric Department of HSK Hospital and Research Centre over a 12-month period. The collected data were analyzed using Microsoft Excel and appropriate statistical test was used to interpret the data. Results: A total of 101 infants died in our hospital, among them maximum 87 (86.14%) mortality was observed in early neonatal period. Causes of mortality were classified as direct and antecedent causes. The most common direct cause was found to be birth asphyxia 35 (34.66%) followed by respiratory distress syndrome 15 (14.85%) and meconium aspiration syndrome 15 (14.85%). Congenital cardiomyopathy (n = 3) was the most common congenital anomaly. 79.35% of the neonates had low birth weight and 20.65% were small for gestational age. Conclusion: With birth asphyxia being the most common cause, education and training regarding neonatal resuscitation will play a major role in decreasing the neonatal mortality.
ABSTRACT
Introduction: In India 7.7% of the total population is constituted by 60+ year age group. With the advancement of medical sciences and improvement of social conditions there has been great change in recent times. The purpose of this study is to delineate the socio demographic profile of geriatric population of rural area. Methodology: A cross sectional study was done on 2000 elderly in the rural field practice area of Adichunchangiri Institute of Medical Sciences,BGNagar, Mandya district using a structured and pretested Performa. Results: The study revealed that 68.5% of the elderly were in the age group of 60-69 years and 96% were Hindus. Majority of the subjects belonged to class IV andV of Modified B G Prasad socio economic classification. 90 .6% of the men were dependent on agriculture. Conclusion: The study provides data to plan services and programmes for betterment of aged, hope this study yields valuable information required for the design of the services to be provided for this special group.
